我场从1959年以来进行的生产试验表明,农田、山坡撩荒地施肥栽参的产量和商品参的质量都比陡坡毁林栽参地高。桓仁县下甸子大队参场,由于实行了坡耕地施肥栽参和参粮轮作,2年生人参产量稳定在每平方米2斤左右,远远超当地毁林栽参的产量(每平方米1～1.51斤),栽参后轮作玉米亩产超过了千斤。 Production tests conducted in our field since 1959 show that the yield and product quality of fertilized ginsengs on farmland and hillsides are all higher than those on steep slope deforestation ginsengs. Huanren County under the Dianzi brigade participating field, due to the implementation of sloping land fertilization and ginseng rotation, 2-year-old ginseng production stable at 2 kg per square meter, far exceeding the local deforestation ginseng production (1 per square meter ~ 1.51 kg), planting ginseng rear mung per mu more than a kilogram.
